2018-04-16drivers/pc80/tpm: Add some optional delay to tis_readresponse()Bill XIE
Certain TPMs (observed on Infineon SLB9635 installed on revolve 810 g1) seem to need some delay between tis_wait_valid() and tis_has_valid_data(), or tis_has_valid_data() may invalidly return 0, ending the loop immaturely with some bytes left unread, and fail to pass the check below, causing the current command not finalized by tis_command_ready(), and blocking any later tis_wait_ready(). This time the added delay is controlled by a Kconfig option TPM_RDRESP_NEED_DELAY.

2016-10-02Kconfig: Update default hex values to start with 0xMartin Roth
Kconfig hex values don't need to be in quotes, and should start with '0x'. If the default value isn't set this way, Kconfig will add the 0x to the start, and the entry can be added unnecessarily to the defconfig since it's "different" than what was set by the default. A check for this has been added to the Kconfig lint tool.

2015-10-27tpm: acpi: Add support for TPM PIRQDuncan Laurie
With SPI TPMs there is no SERIRQ for interrupts, instead it is a PIRQ based interrupt. The TCG PC Client Platform TPM Profile Specification says it must be active low and shared. This can be enabled with the CONFIG_TPM_PIRQ option that will specify the interrupt vector to report for the TPM.

2015-04-10tpm: Add ramstage driver and interrupt configurationDuncan Laurie
This adds a ramstage driver for the TPM and allows the interrupt to be configured in devicetree.cb. The interrupt vector is set like other PNP devices, and the interrupt polarity is set with a register configuration variable. These values are written into locality 0 TPM_INT_VECTOR and TPM_INT_ENABLE and then all interrupts are disabled so they are not used in firmware but can be enabled by the OS. It also adds an ACPI device for the TPM which will configure the reported interrupt based on what has been written into the TPM during ramstage. The _STA method returns enabled if CONFIG_LPC_TPM is enabled, and the _CRS method will only report an interrupt if one has been set in the TPM itself. The TPM memory address is added by the driver and declared in the ACPI code. In order to access it in ACPI a Kconfig entry is added for the default TPM TIS 1.2 base address. Note that IO address 0x2e is required to be declared in ACPI for the kernel driver to probe correctly. BUG=chrome-os-partner:33385 BRANCH=samus,auron TEST=manual testing on samus: 1) Add TPM device in devicetree.cb with configured interrupt and ensure that it is functional in the OS. 2) Test with active high and active low, edge triggered and level triggered setups. 3) Ensure that with no device added to devicetree.cb that the TPM is still functional in polling mode.
